Be` itknown` that I, JEREMY W. BLIss, of

the-city.` andgrcountyof Hartfordland State of"v Connecticut, havew` invented certain new and` useful Improvements inthe Striking Mechanism of Alarm-Bells or* Signal- G-ongs, asthey are now `usually-termed, and also in the ArrangementA of SuchvMechanism,- andil that the following specication,

takenin` connectionlwith the drawings, is `afull, clear, andexact description thereof.`

In the drawings Figure l is an elevation of the bell ull. Fig. 2 is a plan of the striking mec anism and bell standard, the bell being removed, and Eig: Bis asection through the center ofthe-bell pullgvbelland striking apparatus.

The nature of the iirst part of my inven# tion consists in arranging the whole striking mechanism of the bell within the bell itself when the line in which the actuating force moves is at right angles or nearly so to the plane which touches the edge of the bell, or

in other Words, the first part of my invention consists in arranging the whole of the `striking mechanism under cover (or protection) of the hollow of the bell substantially as shown in the drawings when the line in which the actuating wire or spindle travels is parallel to the axis of the bell or nearly so, and the nature of the second partof my invention consists in a eculiar combination of mechanism substantlally such as is hereafterdescribed for actuating a bell hammer. My improvements have been devised with special reference to house bells, in which it is important that the mechanism should be concealed for lthe sake of finish and neatness and when it is desirable that it should be protected from ignorant domestics who might interfere with and disarrange unprotected striking mechanism, and it is obvious that, other things being equal, the cheapest way of protecting and concealing the mechanism is by means of the bell itself. My improvement may however be applied in other localities. e

In thedrawin s I have shown the bell `as applied to one si e of a door or wall and the pull `or knob as projecting from the other side, but desire it to` be understood that the knob may be at any distance or in any convenient spot so long as the connecting wire or rod last in the series that comes from the knob and nearest to the bell leads to the JEREMY; Wi.

Th1s`meca s consists of a rock shaft arm g pivoted at` h,

link such as A pin j in'thisarmabuts I against another pinkprojecting `from the surface of a slide] which is free tomoveto` and fro across the face plate in a right line",`

being held in place by anysuitable guides` A tail or projection m is attached tothe slide e plate and to the outer `endof it isattachedl one end of a spring n, the other end of which y is attached to a `A-stud secured `to :the face* plate. This spring when free to act causes the slide to move in adirection opposite to that indicated by arrow Upon theslide is pivoted a swinging catch ovvhich isforced by a spring p to bear lagainsta stud g also attached `to the slide. i i f w The hammer 1^ is "mounted1 on` `a Wire which moves on a center atft,`and the ham mer is forced toward the bellby a springt@` taking hold `of a wire attached tothe hamf mer wire and having its other end secured to the face plates. When the parts arealll in the position shown in Fig.` 2 the tail ofthe hammer wire rests behind the projecting parts of the swing catch 0;; Whenlthe knob is pulled the rock shaft descends towardthe face plate, the pin upon it causes the stud to move in the directlonfof the `arrow .e and the swing `catch acting on the; tail ofthe hammer Wire moves the `hammer away from` the bell until the catch passes beyondthe end 1y of the tail, releasing it, owingto the `fact that the tail moves inan arcofa circle and y the catch in a right line. `3 When the tail is released the spring u forces thefhammer to strike the bell, and `when the bell pull is e A released the spring n connect d tothe slide carries it back to its position as shown in Fig. 2. The swing catch owing to its shape and pivoting dodges by the hammer tail and being forced by the spring p to resume its former relative to the slide. The rock shaft arm is returned to its place by the spring n acting through the slide and pin la upon the pin 7' and the spindle assumes its old position owing to the force exerted upon it by the spring which surrounds it.

Now it will be perceived that all of the mechanism is Yinclosed (or protected) and covered by the bell itself and also protected by it, that unless the eye is placed close'to the surface on which the bell is mounted none 'of it is visible and also that by removing the bell the whole apparatus is in plain sight and accessible for the purpose of cleaning or repair.

The mechanism described' is sufficiently simple, but other mechanism may be substituted for it andstill be within the principles of the first part of ymy invention, provided such mechanism is substantially inclosedby and concealed under, the cavity of the bell and'is so constructed that it may be actuated by a wire or spindle whose line of motion is parallel to the axis of the bell or nearly so.

I claim as Vof my inventionl. Arranging the striking mechanism of a bell substantially within the hollow of the bell as specied when the wire which actuates that mechanism mov'es in lines parallel to the axis of the bell or nearly so-as described.

2. I claim a rock shaft arm arranged and moving with rreference to the. bell substantially as described in combination with` a slide, a swing catch and a hammer and hammer wire and proper springs the whole constituting a striking apparatus substantially suchy as herein set forth.

In testimony whereof I have hereunto subscribed my name-in the city of Hartford on this l2 day of November, 1859.
